12 Claims, No Drawings TEXTILE FINISH USING A COMBINATION OF AN AMINOPLAST RESIN AND MONOMETHYLOLDICYANDIAMIDE BACKGROUND OF THE INVENTION 1. Field of the Invention The invention pertains to the art of improving wrinkle recovery and durable press properties by the use of a combination of certain organic chemicals.

2. Description of the Prior Art In the textile finish field, cellulosic fabrics are treated with cross-linking reactants, for example, the amino-.

plast resins, to improve elasticity, i.e., wrinkle recovery, durable press properties, etc. However, the use of such treatment often is accompanied by a loss of strength and abrasion resistance. Various attempts have been made to overcome the undesirable loss of strength and abrasion resistance effects which accompany resin treatments. However, these attempts have been merely partially successful. In certain instances they depend on the use of less resin and thus the treated fabrics show poorer performance in desired characteristics. This invention is based on a process for improving textile finishes which involves the use of monomethyloldicyandiamide in combination with the normally used aminoplast resin finish whereby more desirable wrinkle recovery and durable press properties are achieved with greatly decreased loss of strength and abrasion resistance than is obtained when the aminoplast resin is applied in the absence of monomethyloldicyandiamide or when large amounts of phosphoric acid are used with the combination. US. Pat. No. 3,209,164; 3,079,279; 3,260,565 and 3,304,312 deal with ethyleneurea derivatives as wrinkle retardants or creaseproofing agents for textiles. The data in Table IV compares the crease-proofing properties of monomethyloldicyandiamide with other monofunctional agents. U.S. Pat. No. 2,582,961 teaches the use of monomethylolidcyandiamide and a resin with large amounts of phosphoric acid for flameproofing fabrics and improved crease and shrinkage resistance. Table V illustrates the improvement of my invention wherein the acid is reduced to less than 4% of the monofunctional reactant bath an improved tensile strength and flex abrasion are obtained.

SUMMARY OF THE INVENTION The invention is a process for improving cellulosic textile material by imparting improved wrinkle recovery and durable press properties to the textile material accompanied by minimal loss of strength and abrasion resistance which comprises applying a combination of an aminoplast resin crosslinking agent, monomethyloldicyandiamide, an accelerator, and less than 4% acid to the material and the material so treated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention is a process for improving textiles which involves the use of monomethylolidcyandiamide in combination with the normally used aminoplast resin finish and less than 4% acid whereby more desirable wrinkle recovery and durable press properties are achieved with greatly decreased loss of strength and abrasion resistance. Monomethyloldicyandiamide is a condensation product of equal molar amounts of form- 2 aldehyde and dicyandiamide. The synthesis is described in J. Prakt. Chemie, (2) Vol. 77 pg. 537 (1908).

The monomethyloldicyanadiamide may be applied to the fabric either separately as a pretreatment followed by drying of the fabric before applying the aminoplast resin finish by a conventional method; or the monomethyloldicyandiamide may be applied simultaneously with aminoplast resin in the same bath. Thus, the combination is as effective in minimizing strength and abrasion loss when applied in the same bath as when applied as a pretreatment.

The normally encountered cross-linking agents identified as aminoplast resins may be used in the process. For example, as used herein the expression aminoplast resin includes many of the better known textile finishing resins classifiable as amino resins such as melamine formaldehyde condensates, guanamine formaldehyde condensates, triazole formaldehyde condensates, urea formaldehyde condensates, thiourea formaldehyde condensates, cyclic urea formaldehyde condensates, for example, 1,2-propylene urea formaldehyde condensates, 1,3-propylene urea formaldehyde condensates, and their corresponding thiourea derivatives and the alkylated, such as methylated, ethylated, and the like.

The following melamine formaldehyde resins are examples of resins useful in the process of my invention: tris(methoxymethyl) melamine, tris(methoxymethyl) dimethylol melamine, hexakis(methoxymethyl) melamine, bis(methoxymethyl) methylol melamine and the like. Examples of suitable guanamine formaldehyde condensates include the formaldehyde and alkylated formaldehyde condensates of methoxyacetoguanamine, propoxyacetoguanamide, butoxyacetoguanamine, lactoguanamine and others of the type known in the prior art and particularly those described in US. Pat. No. 2,887,409. Examples of urea and cyclic urea formaldehyde: resins contemplated by the present invention are dimethylol urea, methylated methylol urea, methylated methylol thiourea, dimethylol 1,2-propylene urea, dimethylol ethylene urea, dimethylol ethylene thiourea, dimethylol 1,3-propylene urea, methylated dimethylol 1,3-propylene urea, and the like. Examples of triazone formaldehyde resins include dimethylol tetr'ahydro-5-ethyl-s-triazone-2, dimethylol tetrahydro-5(2-hydroxyethyl)-s-triazone-2 and tetramethylolethylene-S ,5 '-bis( tetrahydro-s-triazone-2 i As illustrative of the aminoplast resin useful in the process of the invention, examples are shown below with the results using (1) dimethyloldihydroxyethyleneurea, (2) bis(methoxymethyl)uron; 15% hexakis(methoxymethyl)-melamine, (3) methylated hexamethylolmelamine with a crude urea component (uron), (4) polymethylolurea having 2.8 moles of combined formaldehyde. The preferred resin is dimethyloldihydroxyethyleneurea.

The application of the reagents to the fabric is made under conventional conditions using also conventional accelerators, for example, a combination of 30% magnesium chloride and 2.5% aluminum chloride in water. In the process of the invention effective amounts of the monomethyloldicyandiamide range from about 4 to about 10% of the weight of the material for improving wrinkle resistance with minimal loss in textile strength and abrasion resistance, with a preferred range being about 6 to 8%. Effective amounts of the aminoplast resin for improving wrinkle resistance with minimal 3 loss in textile strength and abrasion resistance range from about 5 to about 35% of the weight of the matcrial, with a preferred range being about to 25%.

in the following examples which serve to illustrate the invention, the terms MMD and DMDHEU are used 4 but with the DMDHEL' treatment omitted. All the fabric samples are then dried at 225F. for two minutes, cured for one minute at 350 and finally tested. for wrinkle recovery. strength and abrasion resistance. The data on these measurements are presented in Table 1.

EXAMPLE 1 Application of MMD Monofunctional Reactant and DMDHEU Crosslinking Agent from Separate Baths A. Three pad baths containing 15, 20 and 25 percent DMDHEU and 2.7, 3.6 and 4.5 percent accelerator respectively, are prepared. *Accelerator is aqueous solution containing 30% magnesium chloride and 2.5% aluminum chloride.

B. Five pad baths containing 3, 5, 6, 7 and 8 percent MMD and 1.0, 1.6, 1.9, 2.2 and 2.6 percent phosphoric acid (85%), respectively, are prepared.

Each of the latter four MMD baths is applied by standard padding procedure to three samples each of 80 X 80 cotton percale 12 samples total) with a wet pickup of 80% on the weight of the fabric and the treated fabrics then dried. These treated samples along with sam ples in which the MMD treatment is omitted are then padded with DMDHEU baths of A above to a wet pickup of 80% on the weight of the fabric. The first pad bath (3% MMD) is similarly applied to cotton percale The results in Table 1 illustrate that treatment with MMD alone makes no significant difference in wrinkle recovery, strength or abrasion resistance. DMDHEU alone can cause about 90% loss in abrasion resistance and about 60% loss in tensile strength while giving improvement in wrinkle recovery. The results in Table 1 further illustrate improvement in tensile strength and abrasion resistance with little or no decrease'(sometimes an increase) in wrinkle recovery properties when cotton textile is treated with DMDHEU after pretreatment with MMD. Thus, application of 7% MMD and then 20% DMDHEU, compared to 20% DMDHEU and no MMD imparts an increase in wrinkle recovery from 254-275, an increase in strength from 26 X 17 to 39 X 27 and an increase in abrasion resistance from 37 X 25 to 141 X 168.

EXAMPLE 2 Application of MMD Monofunctional Reactant Simultaneously with DMDHEU Crosslinking Agent An aqueous pad bath containing 20% DMDHEU and 3.6% accelerator* is prepared and divided into five portions. The first portion is used with no further modification. To the remaining four portions is added MMD to concentrations of 5, 6, 7 and 8% and phosphoric acid (85%) to concentrations of 1.6, 1.9, 2.2 and 2.6 percent respectively. Each of the five resin baths is applied by standard padding procedure to X 80 cotton percale with wet pick up of 80% on the weight of the fabric. The treated samples are dried for two minutes at 225F.. cured for one minute at 350F., and then tested for wrinkle recovery, strength and abrasion resistance. The data on these measurements are presented in Table ll.

* Accelerator is aqueous solution containing 30% magnesium chloride and 2.5% aluminum chloride.

One portion of each is used with no modification: to another portion of each is added MMD to a concentration of 7% and phosphoric acid (85%) to a concentration of 2.2%; to a third portion of MMD Monofunctional Reactant and DMDHEU Crosslinking Agent Applied Simultaneously From Comm on Bath.

MMD, is essentially as effective in minimizing tensile strength loss and abrasion resistance loss when applied simultaneously with the croslinking reactant as when applied as a pretreatment (as in Example 1).

EXAMPLE 3 Application of MMD Monofunctional Reactant with Miscellaneous Crosslinking Reactants each of the original solutions is added MMD to a concentration of 8% and phosphoric acid (85%) to a concentration of 2.6%.

Each of these nine baths is applied by standard padding procedure to 80 X 80 cotton percale with a wet Solutions Containing of each of the following pick-up of 80% on the weight of the fabric. The treated crosslinking reagents are prepared: bis(rnethoxymethyl)-uron hexakis(methoxymethyl)melamine (85:15), methylated hexamethylolmelamine crude uron component (75:25) and polymethylolurea containing 2.8 moles of combined formaldehyde (4648% solids). To each of these is added accelerator* to a confabrics are dried for two minutes at 225F., cured for one minute at 350F., and then tested for wrinkle recovery and loss in tensile strength and abrasion resistance.
